The summary of ANOVA 2x2

93 Communication material is more effective than Textbook material to teach writing. b. Students having high learning motivation compared with ones having low learning motivation Because the q o between rows 4.43 is higher than q table 2.88, the difference of the means between rows is significant. It means that there is a significant difference between students having high and low learning motivation in writing skill. The mean score of the students having high learning motivation 77.4 is higher than the mean score of the students having low learning motivation 72.3. It can be summarized that students having high learning motivation have better writing skill than the students having low learning motivation. c. Comparing students having high learning motivation taught using Computer Based Communication and Textbook material Because q o between columns for high learning motivation 9.30 is higher than q table 3.00, the difference between the students having high learning motivation taught using Computer Based Communication material and the students having high learning motivation taught using Textbook material is significant. It means that the students having high learning motivation taught using Computer Based Communication material differ significantly from the students having high learning motivation taught using Textbook material. The mean score of the students having high learning motivation taught using 94 Computer Based Communication material 82.33 is higher than of those taught using Textbook material 72.2. It can be concluded that the Computer Based Communication material is more effective than Textbook material to teach writing for students who have high level of learning motivation. d. Comparing students having low learning motivation taught using Computer Based Communication and Textbook Material Because q o between columns for low learning motivation 3.26 is higher than q table 3.00, the difference between students having low learning motivation who are taught using Textbook material and the students having low learning motivation who are taught using Computer Based Communication material is significant. The mean score of students having low learning motivation who are taught using Computer Based Communication material 71.2 is lower than that of taught using Textbook material 73.67. It means that Textbook material is more effective than Computer Based Communication material to teach writing for the students who have low learning motivation.

D. Discussion of the Result

The following section describes some explanations related to the findings of this research by considering the result of data analysis above: 95 1. Computer Based Communication material is more effective than Textbook material to teach writing Computer Based Communication can stimulate students to write. Computer Based Communication can generate students‟ ideas, make them have real communication and encourage them to practice writing with the internet as the media. Students‟ attitude toward the use of Computer Based Communication is positive. By applying this material in teaching writing, the students can produce the better quality of writing when they work by computer individually. Danielsen 2000: 116 find that the Computer Based Communication makes an individual comfortable which allows a communicative partner to open up more easily and be more expressive. It seems that the learning process runs more enjoyably and occurs creatively because they can deliver their opinion in computer without any border. They have more chance to build up their confidence in practicing their ability. Bandura 1997: 175 asserts that in a responsive environment that rewards performance achievements, the outcomes poeple expect depend heavily on their self-confidence that they can perform the skill. Another benefit is also delivered by Kang and Dennis 1995: 25, by learning from computer, the students become active learners in a one-on-one environment. Computers can incorporate various learning strategies to accommodate a variety of learning styles. Different from Computer Based Communication, Textbook writing material that is characterized by teacher-led interactions makes the
